Research on tricuspid valve dysplasia
Tricuspid valve dysplasia is a congenital heart condition in which the tricuspid valve—the valve between the right atrium and the right ventricle—is not properly developed. As a result, the valve does not close completely, causing some of the blood to flow back into the right atrium instead of toward the lungs. This causes overload and enlargement of the right side of the heart.
These dog breeds are at increased risk of tricuspid valve dysplasia:

What are we researching?
Tricuspid valve dysplasia is a hereditary condition. Genetic testing allows us to identify the hereditary factors and contribute to better breeding strategies, so that future generations are born healthier.
How do we do that?
During the physical examination, which includes listening to the heart (auscultation), initial indications of a possible heart defect, such as a heart murmur, can be found. To further assess the heart, our experienced cardiologists perform an echocardiogram. For this, a small patch of fur is shaved on both sides of the chest. If the examination reveals any indications of heart disease, we will of course inform the owner of the dog immediately. They will also receive a detailed ultrasound report.
With owner permission, we can also take a small blood sample during the screening for DNA storage. This DNA can be used for future genetic research.
